Digital Metrology regularly works with metrology instrument providers and their end users to solve tough problems. This recent project is a great example. Digital Metrology developed the NozzleView software to better understand the geometry within fuel injector spray holes. These geometries are critical to fuel injector performance, but until recently they have been very difficult to measure and analyze. The NozzleView software lets users to analyze and explore the shape of each spray hole throughout its length, and to visually interact with the data to gain a better view, and better understanding, of the surface geometries.
